High-frequency (HF) surface wave radars provide a unique capability to detect targets far beyond the conventional microwave radar coverage but also could contribute to the development and improvement of Tsunami Early Warning Systems. This paper describes the simulation of tsunami related signatures observed by HF radar at long ranges in case of a tsunami travelling towards the coast. A tsunami ...

OBJECTIVE To describe the distribution of mortality among internally displaced persons during two and a half months after the Indian Ocean tsunami, 2004. DESIGN Cross sectional household survey with retrospective cohort analysis of mortality. SETTING Camps for internally displaced persons due to the tsunami in an eastern coastal district of Sri Lanka. PARTICIPANTS 3533 people from 859 hou...

This paper considers turbulence effects on tsunami runup the shore in simulations using system of three-dimensional Navier–Stokes equations. The propagation and are studied by solving problem a wave propagating nonuniform-bottom pool collapsing with barrier. To solve this problem, we used model, RANS SST (Reynolds-averaged shear stress transport). We compared profiles at different times during ...

The 2011 Great East Japan earthquake and tsunami was a magnitude 9.0 Mw event that destroyed most structural tsunami countermeasures. However, approximately 90% of the estimated population at risk from the tsunami survived due to a rapid evacuation to higher ground or inland. Thus, tsunami evacuation is the most effective measure to reduce casualties. In this paper, we applied a new developed e...

Throughout history, large tsunamis have frequently affected the Sanriku area of the Pacific coast of the Tohoku region, Japan, which faces the Japan Trench. Although a few studies have examined paleo-tsunami deposits along the Sanriku coast, additional studies of paleo-earthquakes and tsunamis are needed to improve our knowledge of the timing, recurrence interval, and size of historical and pre...

Identification of Tsunami deposits has long been a controversial issue among geologists. Although there are many identification criteria based on the sedimentary characteristics of unequivocal Tsunami deposits, the concept still remains ambiguous. Apart from relying on some conventional geological, sedimentological, and geoscientific records, geologists need some alternative "proxies" to identi...

Each year, about 60 000 people and $4 billion (US$) in assets are exposed to the global tsunami hazard. Accurate and reliable tsunami warning systems have been shown to provide a significant defence for this flooding hazard. However, the evolution of warning systems has been influenced by two processes: deadly tsunamis and available technology. In this paper, we explore the evolution of science...

Amurang Bay is a coastal area of South Minahasa Regency which densely populated but faces the subduction zone North Sulawesi has potential to generate earthquakes that trigger tsunami. The process tsunami disaster occurred quickly, impact was very destructive and caused many casualties. This study aims determine propagation waves with worst scenario Mw 8.5 in Bay. Numerical methods COMCOT softw...

The Makran coast is extremely vulnerable to tsunamis and earthquakes due to the presence of three very active tectonic plates namely, the Arabian, Eurasian and Indian plates. On 28 November 1945 at 21:56 UTC, a massive Makran earthquake generated a destructive tsunami in the Northern Arabian Sea and the Indian Ocean. The tsunami was responsible for loss of life and great destruction along the c...
